chore(newos4): commit accumulated maintenance outputHEADv4.6.156main

The daily collector and the feedback pipeline had left 57 modified files uncommitted (skills,
modules-index, CHANGELOG, feedback decisions, debug counters). The public mirror publishes git
HEAD, so without this the published repo stayed behind the tree - and it blocked the publisher
outright once uncommitted subtrees started failing loudly.

+/**
+ * scripts/test-agents-lifecycle.js — regression test for the /agents/ VFS leak.
+ *
+ * Bug history: killAgent() / AgentRegistry.unregisterAgent() called
+ * fs.deleteFile('agents/<id>') on a DIRECTORY. VirtualFileSystem.deleteFile()
+ * is file-only (returns false for dirs), so the call silently no-op'd and
+ * /agents/<id>/ (status.json, inbox.json, outbox.json) leaked forever.
+ * Fixed by using fs.rm() (dispatches file|dir → trash) + bounded .trash.
+ *
+ * Loads the PRODUCTION artifact (modules/core/core-bundle.js), not the sources,
+ * because main.html serves the bundle — a source-only fix is invisible in prod.
+ *
+ * Run: node scripts/test-agents-lifecycle.js     (exit 0 = pass)
